Achalasia is a rare but serious swallowing disorder that affects the esophagus, the tube that carries food from your mouth to your stomach. Many people first notice symptoms like difficulty swallowing or food “getting stuck,” but often confuse it with acid reflux or indigestion. However, achalasia is very different and requires proper diagnosis and management.
If you are experiencing swallowing problems or unexplained chest discomfort, understanding achalasia can help you take the right steps early.
What is achalasia and how does it affect swallowing?
Achalasia occurs when the muscles of the esophagus stop working properly due to nerve damage. Normally, the esophagus uses rhythmic contractions to push food down into the stomach. At the same time, a valve at the bottom called the lower esophageal sphincter (LES) relaxes to allow food to pass through.
In achalasia, two key problems happen:
The esophagus loses its ability to push food downward
The lower esophageal sphincter does not relax properly
As a result, food and liquids cannot move easily into the stomach. Instead, they remain stuck in the esophagus, which can stretch and become enlarged over time.
What are the common symptoms of achalasia?
Symptoms of achalasia usually develop slowly and worsen over time. Many people ignore early signs, thinking it is a minor digestive issue.
Common symptoms include:
Difficulty swallowing (dysphagia), especially with both solids and liquids
Feeling like food is stuck in the chest or throat
Regurgitation of undigested food or saliva
Chest pain that comes and goes
Heartburn-like discomfort
Coughing, especially at night
Unintended weight loss
In some cases, food can enter the lungs, leading to repeated chest infections or pneumonia. Therefore, it is important not to ignore these symptoms.
What causes achalasia in the body?
The exact cause of achalasia is not fully understood. However, researchers believe it is linked to the loss of nerve cells in the esophagus that control muscle movement.
Several possible causes have been suggested:
Autoimmune reactions where the body attacks its own nerve cells
Viral infections that damage esophageal nerves
Genetic factors in rare inherited conditions
In most cases, there is no clear single cause. However, the end result is the same—impaired movement of food from the esophagus to the stomach.
Who is at risk of developing achalasia?
Achalasia can affect anyone, but certain factors may increase the risk.
People between the ages of 25 and 60 are more commonly affected. It can also occur in individuals with specific medical conditions such as autoimmune disorders or rare genetic syndromes like Allgrove syndrome.
Unlike many digestive diseases, lifestyle factors such as diet or weight are not direct causes of achalasia.
How is achalasia different from acid reflux (GERD)?
Many people confuse achalasia with acid reflux, also known as gastroesophageal reflux disease (GERD). However, the two conditions are quite different.
In achalasia, food remains in the esophagus because it cannot move into the stomach.
In GERD, stomach acid flows back up into the esophagus.
Although both conditions can cause chest discomfort and regurgitation, their underlying causes and treatments are completely different. This is why accurate diagnosis is essential.
How is achalasia diagnosed?
Doctors use several tests to confirm achalasia and rule out other conditions.
Common diagnostic methods include:
Esophageal manometry, which measures muscle contractions in the esophagus
Barium swallow X-ray, which shows how food moves through the esophagus
Endoscopy, which allows doctors to examine the esophagus and stomach directly
These tests help determine how well the esophagus is functioning and whether the lower esophageal sphincter is opening properly.
How is achalasia treated and managed?
There is currently no cure for achalasia. However, treatments can significantly improve symptoms and help food pass into the stomach more easily.
Treatment options include:
Endoscopic procedures such as balloon dilation, which stretches the lower esophageal sphincter
Botox injections to relax the muscle temporarily
Minimally invasive surgery like Heller myotomy, which cuts the tight muscle
Peroral endoscopic myotomy (POEM), a newer, less invasive technique
Doctors choose treatment based on the severity of symptoms and the patient’s overall health.
In addition, lifestyle adjustments can help manage symptoms. Eating slowly, chewing food thoroughly, and drinking water during meals can improve swallowing.
What complications can achalasia cause if untreated?
If left untreated, achalasia can lead to serious complications.
Food buildup in the esophagus can cause stretching and enlargement. Over time, this may increase the risk of infection or aspiration, where food enters the lungs.
Chronic inflammation can also raise the risk of esophageal cancer, although this is rare.
Therefore, early diagnosis and ongoing management are crucial.
What are common mistakes people make with achalasia?
One common mistake is assuming the condition is just acid reflux and self-medicating with antacids. This delays proper treatment.
Another mistake is ignoring symptoms like persistent swallowing difficulty or weight loss. These signs should always be evaluated by a doctor.
Some people also avoid seeking help because symptoms develop slowly. However, early treatment can prevent complications and improve quality of life.
Conclusion: How can you live with achalasia effectively?
Although achalasia has no cure, it can be managed successfully with the right treatment and lifestyle adjustments. Most people experience significant symptom relief after medical intervention.
If you notice ongoing swallowing problems, regurgitation, or chest discomfort, it is important to seek medical evaluation. Early diagnosis can help you avoid complications and maintain a better quality of life.
In short, understanding achalasia and acting early makes a big difference in long-term health and comfort.
